API

http.ServerResponse.prototype.json(result, params)

Pass in some result object to be attached as result

• sets Content-Type: application/json; charset=utf-8
• calls res.write(JSON.stringify({ timestamp: Date.now(), result: result, ... }))
• calls res.end()

Optional params may be an object such as this

{
    debug: false        // set `true` if the response should be pretty-printed
                        // also, stack traces should not be removed
  , stringified: false  // set `true` if the result is already `JSON.stringify()`'d
}

http.ServerResponse.prototype.meta(key, value)

Add a field to the "header" (sibling of result, success, etc)

http.ServerResponse.prototype.error(Error)

Add an Error to the error array and set success to false.

Note: By default, stack traces will be removed from errors.
